Choosing a Brightness Level for Your iPhone Screen
You can manually or automatically set the brightness on your iPhone to match the ambient light conditions. Who doesn’t want a bright, vibrant iPhone screen?
Slide this control to adjust screen brightness.
Alas, the brightest screens exact a trade-off. Before you drag the brightness slider to the max, remember that brighter screens sap the life out of your battery more quickly.
It’s good practice to tap the Auto-Brightness control so that it is On. It adjusts the screen according to the lighting conditions around the iPhone while being considerate to your battery.
